Application Advice; Maintenance & Service - Skil 4900 Instructions Manual

• Adjusting sawing speed to material used 6
! if the tool does not run with wheel C 2 in
position 1, select a higher sawing speed and
lower the sawing speed while the tool runs
• Mounting saw blade 7
! disconnect the plug
- press blade clamp D forward and hold it in that
position
- insert blade (with teeth facing down or up) to full
depth
- release blade clamp D
- pull out blade somewhat until clamp D clicks into a
square position
- push in and pull out blade to check whether it is
locked correctly
! ensure that blade clamp D 2 is tight before
making a cut (a loose clamp may cause the tool
or blade to slip with loss of control as a result)
! ensure that the front end of the blade extends
through footplate E for the entire stroke length
• Removing saw blade 8
- press blade clamp D forward and hold it in that
position
- pull out blade
- release blade clamp D
• Adjustable footplate 9
- footplate E tilts in order to keep as much of its
surface in contact with the workpiece
- adjust footplate by holding the saw fi rmly and turning
footplate to desired position
• Blade storage compartment 0
- ensure that storage compartment F is closed to
prevent blades from falling out
• Operating the tool
! securely clamp the workpiece
- mark the cutting line on the workpiece
- select desired sawing speed with wheel C 2
- connect plug to power source (light B turns on
indicating that the tool is receiving power) !
- hold the tool with one hand on handle G 2 and the
other on the insulated barrel grip H 2
- switch on the tool
! the tool should run at full speed before the blade
enters the workpiece
- guide the tool along the marked cutting line
- keep footplate E 2 fi rmly against the workpiece to
minimize counter-force and vibration
• Holding and guiding the tool
! while working, always hold the tool at the grey-
coloured grip area(s) @
- keep ventilation slots J 2 uncovered
- do not apply too much pressure on the tool; let the
tool do the work for you
! ensure that the saw blade extends beyond the
work throughout the stroke #
• Adjusting effective stroke length $
- use both adjustment screws K for sliding footplate E
forward/backwards in order to enlarge/reduce the
effective stroke length
! do not attempt to adjust the effective stroke
length with screw L which is pre-set at
manufacturing
• Plunge cutting %a
Plunge cuts can be made in wood and other soft
materials without pre-drilling a hole
- select position 1, 2 or 3 with wheel C
- mark desired cutting line on the workpiece
- position the tool with one edge of footplate E fi rmly
against the workpiece
- place the tip of the blade (not running) on the cutting
line
- tilt the tool so that the blade does not touch the
workpiece
- switch on the tool and carefully engage the moving
saw blade into the workpiece
- after the blade has penetrated through the workpiece
continue sawing along the marked cutting line
! do not make plunge cuts in metal materials
• For easier plunge cutting, use a thick saw blade, or
mount the blade with the teeth facing upward and hold
the saw upside down as illustrated %b

APPLICATION ADVICE

• Use the appropriate saw blades ^
• When cutting metals, lubricate saw blade regularly with
oil
• Splinter-free cutting
- cover cutting-line with several layers of wide tape
before cutting
- always face the good side of the workpiece down
• For more tips see www.skileurope.com
• Vibration level
The vibration emission level stated at the back of this
instruction manual (indicated by an asterisk) has been
measured in accordance with a standardised test given
in EN 60745; it may be used to compare one tool with
another and as a preliminary assessment of exposure to
vibration when using the tool for the applications
mentioned
- using the tool for different applications, or with
different or poorly maintainted accessories, may
signifi cantly increase the exposure level
- the times when the tool is switched off or when it is
running but not actually doing the job, may
signifi cantly reduce the exposure level
! protect yourself against the effects of vibration by
maintaining the tool and its accessories, keeping
your hands warm, and organizing your work
patterns
MAINTENANCE / SERVICE
• Always keep tool and cord clean (especially the
ventilation slots J 2)
! disconnect the plug before cleaning
